Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to an anti-settlement structure that combines compacted short piles with reinforced concrete flooring. Background Technology
[0002] In the construction of large-area factory floors, the traditional method often involves pouring a subgrade on backfilled soil, followed by pouring concrete on top of the subgrade. However, this traditional method is prone to uneven settlement of the backfilled soil, leading to cracks in the poured concrete surface. This poses significant quality and safety risks to the finished floor of the factory's production workshop, and repairs are difficult, often requiring demolition and reconstruction, increasing construction costs and wasting time and materials.

[0005] A settlement-prevention structure combining compacted short piles and a reinforced concrete floor includes a compacted short pile structure and a reinforced concrete floor structure. The compacted short pile structure includes a concrete surface layer and a short pile reinforcement cage. A cast-in-place concrete surface layer is provided on the short pile reinforcement cage to form the compacted short pile structure. The reinforced concrete floor structure includes a graded crushed stone layer, a concrete cushion layer, bottom long reinforcing bars, and a surface reinforcement mesh. The graded crushed stone layer is placed on a compacted subgrade. The concrete cushion layer is placed on top of the graded crushed stone layer. The bottom long reinforcing bars and the surface reinforcement mesh are respectively placed on the upper surface of the concrete cushion layer and inside the concrete surface layer. The boundary of the reinforced concrete floor structure is supported by structural columns and hidden floor beams placed on the structural columns. Multiple evenly distributed compacted short pile structures are placed in the reinforced concrete floor structure to form a settlement-prevention structure.
[0006] Furthermore, the short pile reinforcement cage includes longitudinal bars, spiral stirrups, and stiffening hoops; the longitudinal bars and spiral stirrups are intertwined and welded to form a reinforcement cage skeleton; and stiffening hoops that are welded to the longitudinal bars are provided in the reinforcement cage skeleton.
[0007] Furthermore, the structural column is set on the foundation connecting beam located in the compacted soil layer.
[0008] Furthermore, the upper part of the longitudinal reinforcement is anchored to the bottom long reinforcement in the reinforced concrete floor structure.
[0009] Furthermore, the bottom long steel bars and the surface steel mesh are respectively erected on the upper surface and above the concrete foundation using trestles.
[0010] In summary, this utility model has the following beneficial effects: By designing an anti-settlement structure that combines compacted short piles with reinforced concrete flooring, the compacted short pile structure and reinforced concrete flooring form an integral whole, which can effectively prevent flooring settlement caused by uneven backfill and cracking caused by settlement. It can ensure the functionality of the flooring and extend its service life, guarantee the long-term stability and quality of the flooring in the production workshop, reduce maintenance costs and minimize losses caused by work stoppages and production shutdowns.

[0017] like Figures 1 to 4As shown, a settlement prevention structure combining compacted short piles and reinforced concrete floor slab includes a compacted short pile structure and a reinforced concrete floor slab structure. The compacted short pile structure includes a concrete surface layer 4 and a short pile reinforcement cage 5. The short pile reinforcement cage 5 is provided with a cast-in-place concrete surface layer 4 to form the compacted short pile structure. The reinforced concrete floor slab structure includes a graded crushed stone layer 2, a concrete cushion layer 3, a bottom layer of long steel bars 6, and a surface layer of steel mesh 7. The graded crushed stone layer 2 is placed on a compacted soil layer 1. The concrete cushion layer 3 is placed on top of the graded crushed stone layer 2. The bottom layer of long steel bars 6 and the surface layer of steel mesh 7 are respectively placed on the upper surface of the concrete cushion layer 3 and inside the concrete surface layer 4. The boundary of the reinforced concrete floor slab structure is supported by structural columns 9 and floor beams 8 placed on the structural columns 9. Multiple evenly distributed compacted short pile structures are placed in the reinforced concrete floor slab structure to form a settlement prevention structure. The compacted short pile structure and reinforced concrete floor form a whole, which can effectively prevent the floor from settling and cracking caused by uneven backfill soil. It can ensure the functionality of the floor and extend its service life, ensure the long-term stability and quality of the floor in the production workshop, reduce maintenance costs and reduce losses caused by downtime.
[0018] As a preferred embodiment, such as Figures 2 to 4 As shown, the short pile reinforcement cage 5 includes longitudinal bars 11, spiral stirrups 12, and stiffening hoops 13; the longitudinal bars 11 and spiral stirrups 12 are intertwined and welded to form a reinforcement cage skeleton; the reinforcement cage skeleton is provided with stiffening hoops 13 that are welded to the longitudinal bars 11 to ensure the stability of the load-bearing capacity.
